FIELD: oil and gas industry.
SUBSTANCE: crude oil pipeline pressurizer consists of the single-piece cylindrical metal body and the elongated cylindrical rubber-cord shell, equipped along the axis at the end walls with one sleeve for the air supply to the shell. There are fixing pins on one of the end walls of the shell. The shell is fixed to the end wall of the single-piece cylindrical metal body with the help of one sleeve and fixing pins. The centering elastic elements are fixed on the outer cylindrical wall of the body.
EFFECT: device makes it possible to simplify the fastening of the rubber-cord shell to the single-piece cylindrical metal body, to increase the productivity of repair works on the oil pipeline, due to the elongated cylindrical rubber-cord shell to reduce the working pressure of the air or inert gas inside the shell and to increase the safety of the works, performed on the oil pipeline.
